[0021] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0022] See also Figure 1 、 Figure 2 The embodiment of the utility model provides a laparoscopic field of view exposure airbag, comprising a first fixing belt 1-1, a second fixing belt 1-2, an inflatable chamber 2, a compressed air bag 3, a first traction belt 4-1, and a second traction belt 4-2. The first fixing belt 1-1 is fixed to one side of the inflatable chamber 2, and the other side of the inflatable chamber 2 is connected to the second fixing belt 1-2.

[0023] The compressed air bag 3, the first pulling belt 4-1, and the second pulling belt 4-2 are all located inside the inflatable chamber 2; one end of the first pulling belt 4-1 is connected to the first fixing belt 1-1, and the other end of the first pulling belt 4-1 is connected to one end of the compressed air bag 3;

[0024] One end of the second pulling belt 4 - 2 is connected to the second fixing belt 1 - 2 , and the other end of the second pulling belt 4 - 2 is connected to the other end of the compressed air bag 3 .

[0025] In one embodiment of exposing the airbag under laparoscopic vision, the compressed air bag 3 is provided inside the inflation chamber 2, and the two ends of the compressed air bag 3 are connected to the two ends of the inflation chamber 2 through the first traction belt 4-1 and the second traction belt 4-2 on both sides.

[0026] Specifically, by pulling the first pulling belt 4-1 and the second pulling belt 4-2 to tear the compressed air bag 3, the compressed CO2 gas stored inside the compressed air bag 3 is released to quickly fill the inflation chamber 2, so that the inflation chamber 2 can assist in fully exposing the surgical site.

[0027] In an embodiment of exposing the airbag under laparoscopic vision, the first traction belt 4 - 1 and the second traction belt 4 - 2 are symmetrically distributed at both ends of the compressed airbag 3 .

[0028] Specifically, the first fixing belt 1-1 and the second fixing belt 1-2 are fixed to the outside of the inflatable chamber 2, and the first pulling belt 4-1 and the second pulling belt 4-2 are respectively fixed to the inside of the same position where the first fixing belt 1-1 and the second fixing belt 1-2 are connected to the inflatable chamber 2, so that the first fixing belt 1-1, the second fixing belt 1-2 and the first pulling belt 4-1, the second pulling belt 4-2 are on the same horizontal line on both sides and are subjected to equal force, which can ensure that external force can tear the compressed air bag 3 more easily.

[0029] In addition, the first fixing belt 1-1 and the second fixing belt 1-2 are both formed with operation pull holes 1-3 to facilitate operation of the first fixing belt 1-1 and the second fixing belt 1-2.

[0030] In an embodiment of the airbag exposed under laparoscopic vision, the diameter of the inflatable chamber 2 before inflation and expansion does not exceed 1 cm.

[0031] Specifically, the smaller volume of the inflatable chamber 2 before inflation enables the airbag to be exposed under the laparoscopic field of view and delivered into the abdominal cavity with the help of an ordinary puncture device, which will not increase the difficulty of the doctor's operation or the patient's pain during the operation, and takes into account safety, simplicity and comfort.

[0032] In one embodiment of the laparoscopic field of view exposure air bag, the compressed air bag 3 is filled with compressed CO2 gas.

[0033] Specifically, CO2 is chosen as the compressed gas because CO2 has relatively stable chemical properties, is colorless, odorless, and non-toxic, and generally does not react with other substances. Therefore, even if it leaks, it will not cause serious consequences and has high safety.

[0034] In one embodiment of the airbag exposed under laparoscopic vision, the inflation chamber 2 and the compressed air bag 3 are both made of medical rubber;

[0035] Specifically, the inflation chamber 2 and the compressed air bag 3 are made of medical rubber material because medical rubber material has good air tightness, which can ensure that the CO2 gas inside the inflation chamber 2 and the compressed air bag 3 will not escape, and at the same time has good elasticity and is safe and non-toxic.

[0036] In one embodiment of the laparoscopically exposed airbag, a pre-compression fold 5 is formed on the edge of the inflatable chamber 2. The compressed gas in the compressed air bag 3 enters the inflatable chamber 2, causing the pre-compression fold 5 to expand. The pre-compression fold 5 not only facilitates the deflation of the inflatable chamber 2, but also facilitates rapid expansion after inflation.

[0037] In summary, the present invention includes a fixing strap 1, an inflatable chamber 2, a compressed air bag 3, and a pulling strap 4. The fixing strap 1-1 is fixed to one side of the inflatable chamber 2, and the other side of the inflatable chamber 2 is connected to the fixing strap 1-2. The side of the inflatable chamber 2 connected to the fixing strap 1-1 is also connected to one side of the pulling strap 4-1. The other side of the pulling strap 4-1 is connected to one side of the compressed air bag 3. The other side of the compressed air bag 3 is connected to the pulling strap 4-2, the other side of the inflatable chamber 2, and the fixing strap 1-2. The inflatable chamber 2 of this utility model is equipped with a compressed air bag 3. By pulling the traction strap 4, the compressed air bag 3 is torn, releasing the compressed CO2 gas stored in the compressed air bag 3, rapidly filling the inflatable chamber 2, allowing the inflatable chamber 2 to fully expose the surgical site. The fixing strap 1 and the traction strap 4 each have two parts, placed on the inflatable chamber 2 and the compressed air bag 3 on opposite sides. The fixing strap 1 is fixed to the outside of the inflatable chamber 3, and the traction strap 4 is fixed to the inside at the same position where the fixing strap 1 connects to the inflatable chamber 2. This ensures that the fixing strap 1 and the traction strap 4 are on the same horizontal line and are evenly stressed, ensuring that external forces can easily tear the compressed air bag 3. The utility model is normally in a compressed state, with a diameter of no more than 1 cm. When necessary, it can be inserted into the abdominal cavity through a puncture device, and the fixing belt 1 at both ends can be torn with an instrument to drive the compression and pulling belt 4 to open the compressed air bag 3, so that the compressed gas inside the compressed air bag 3 quickly fills the inflatable chamber 2, causing the inflatable chamber 2 to swell to support the part that needs to be exposed, which is convenient for the surgeon to operate. After the operation is completed, the inflatable chamber 2 is punctured to discharge all the gas in the inflatable chamber 2, and then the inflatable chamber 2 that has restored the compressed state is taken out of the body. The utility model can assist in fully exposing the surgical site, allowing the surgeon to obtain a clearer visual field, and is safe, convenient and easy to operate.

[0038] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
